In some embodiments, the present disclosure provides for various computer engines that may be configured/programmed to generate and/or maintain database(s) for storing and manipulating longitudinal data. Typically, the term “longitudinal data” may be referred to as panel data, allowing to track the same sample (e.g., a population sample) at different points in time, by allowing the measurement of the duration of events, and record the timing of various events. For example, in case of clinical data, an exemplary sample may include individuals, events, repeated cross-sectional data, long-term data, and other similar type of data. For example, longitudinal data can be the weight of a person which may fluctuate over a lifetime. Using this longitudinal data, a histogram of a person's weight over time displays periods of being underweight, normal weight, and overweight. Yet another example, suppose the unemployment rate remained high for a long period of time, one may use longitudinal data to determine if the same group of individuals stays healthy over the entire period or if different groups of individuals move in and out of the healthy state over the time period.

Yet another example, an exemplary inventive longitudinal data engine with an associated exemplary inventive longitudinal database may be configured, for example without limitation, to provide responses to inquiries such as: “For a person in the intensive care unit (ICU) with hypoalbuminemia situation in the 48 hours prior to hospitalization what type of drug would reduce the probability for hypoglycemia event(s) in the next 72 hours?” Typically, an answer to such single question would require numerous database inquiries and programming one or more specialized stored procedures using a standard relational database approach. For example, typically, the standard relational database approach needs to define primary keys and foreign keys. In turn, typically, when records are created in a relational database for several sequential events in a patient life, such events would be recorded in records among numerous tables and rows. Further, typically, such tables would have data for numerous patients. Typically, complex querying code would need to be programmed (e.g., utilizing numerous SQL commands) to isolate sequential events of a single patient which is typically inefficient (time consuming) and, in many cases, not practical (e.g., requiring specialized programming resources).

In some embodiments, the present disclosure provides for an exemplary inventive longitudinal data engine that is associated with an exemplary inventive two-stage data structure arrangement. In some embodiments, the exemplary inventive longitudinal data engine of the present disclosure is configured to include at least:

1) a specialized index structure generation module that may be configured to utilize data structures such as, but without limitation, a cohort index that is a tabular structure configured to allow to identify a desired population (e.g., a population of living subjects (e.g., people (e.g., patients), animals, etc.), a population of objects (e.g., cars, factories, etc.); and

-   -   2) a specialized extraction framework module that may utilize a         time-based structure that may be configured to allow to extract         temporal data (sequential events data) for a selected         population.

In some embodiments, the associated exemplary inventive two-stage data storing schema may be designed to include at least:

-   -   1) a first structure of a corresponding specialized index         structure (e.g., cohort index structure), and     -   2) a second structure that stores corresponding ontology for         each subject or object.

While it is understood that the present disclosure should not be limited to specific examples/embodiments detailed herein, for illustrative purposes only, the exemplary inventive longitudinal data engine with the associated exemplary inventive two-stage data storing schema may be further illustrated in relation to healthcare, clinical data for a population of patients.

In some embodiments, in accordance with the associated exemplary inventive two-stage data storing schema, the exemplary clinical data for the exemplary population of patients is duplicated in both of the structures (i.e., the corresponding cohort index structure and ontologies-storing structure) with different internal representation. In some embodiments, the corresponding cohort index structure is designed as an event-based tabular structure where each event type is represented by a particular data schema (e.g., table). For example, an exemplary event type table may include, for every patient, 1) required field(s) such as a personal unique identifier (e.g., “Patient ID” of Table 1) and a timestamp (e.g., “Time of intake” of Table 1), and 2) one or more other relevant data property(ies), as, for example, without limitation, properties illustratively identified in Table 1 for the event type of medication intake.

TABLE 1 Field Data sample PatientID 12336678 Time of intake Jan. 3, 1998 Medication Name Aspirin Dosage 100 Mg Manufacturer Teva

In some embodiments, the exemplary inventive ontologies-storing structure includes one or more ontologies that can describe one or more respective properties of the particular event type. As illustrated in Table 2, for example, a field “medication code” may be followed by a field of “medication code ontology” containing one or more descriptive ontological variables separated by one or more particular delineators (e.g., symbols (e.g., “#”), characters, etc.).

TABLE 2 Field Data sample PatientID* 12336678 Time of intake* Jan. 3, 1998 Medication Name Aspirin Medication Code 2334519 Medication Code Ontology NSAID # Pain Relief # acetylsalicylic acid # Bayer Aspirin Dosage 100 Mg Manufacturer Teva

In some embodiments, similar data structures having at least the cohort index structure and the ontologies-storing structure may be designed for every type of patient events (e.g., procedures, encounters, surgeries, imaging, diagnostics, demographics, etc.)

In some embodiments, the exemplary inventive longitudinal data engine is configured based on an exemplary inventive extraction framework that can be constructed from a collection of data structures. For example, the exemplary inventive longitudinal data engine may include a separate data structure generated for each object/subject (e.g., every patient). In some embodiments, the exemplary inventive separate data structures can be configured to hold, for each object/subject (e.g., every patient), events sorted by time so as to allow to cause the exemplary inventive longitudinal data engine to generate visual representation that longitudinally tracks events over a period of time as, for example, without limitation, illustrated in FIG. 2. Referring to FIG. 2, the exemplary inventive separate data structures can be configured to store for every event at least:

1) a timestamp,

2) every property value,

3) time period(s) passed between similar event(s) (e.g., blood tests), and

4) time period(s) passed between similar ontology properties (e.g., medications).

In some embodiments, the exemplary inventive separate data structures can be generated utilizing structure hierarchical data elements such as, without limitation, XML, JSON, and similar others. Table 3 provides an exemplary inventive separate data structure designed in XML format.

In some embodiments, the exemplary inventive longitudinal data engine is configured to extract longitudinal data (e.g., the longitudinal clinical data) from the associated exemplary inventive longitudinal database in several stages.

Exemplary First Stage

In some embodiments, at an exemplary first data extraction stage, the exemplary inventive longitudinal data engine is configured to receive a longitudinal query for one or more subjects and/or objects. Then, the exemplary inventive longitudinal data engine is configured to define, utilizing, for example without limitation, one or more SQL-like statements, a population (e.g., relevant subject(s)/object(s)) (item 301 of FIG. 3) and a cohort index structure, as illustrated in Table 3.

TABLE 3 Example 1 Select PatientsID from Patients Where Patient.Gender=‘Female’ Example 2 SELECT p.{grave over ( )}birthdate{grave over ( )},    p.{grave over ( )}gender{grave over ( )},    p.{grave over ( )}race{grave over ( )},    p.{grave over ( )}internalpatientid{grave over ( )},    row_number( ) FROM {grave over ( )}ev_demographics_static{grave over ( )} AS p WHERE p.{grave over ( )}gender{grave over ( )} = ‘male’    and p.{grave over ( )}birthdate{grave over ( )} > ‘2001-03-12’    and p.{grave over ( )}race{grave over ( )} = ‘asian’

FIG. 4 is a snapshot of a computer screen that is configured to be utilized by a user to provide the exemplary inventive longitudinal data engine with parameters to define the exemplary cohort (population) from the exemplary cohort index structure. For example, FIG. 4, shows how the user may submit a query to extract from the exemplary inventive cohort index structure a particular cohort (population) having at least one (1) ontological value of percutaneous transluminal coronary angioplasty (PTCA), and for every one of identified subjects (patients) to pick an age at which first PTCA occurred (e.g., between the age 0 and 120).

Exemplary Second Stage

In some embodiments, at an exemplary second data extraction stage, the exemplary inventive longitudinal data engine is configured to extracts, for example, without limitation, XML/JSON files of the relevant subject(s)/object(s) from the exemplary inventive separate data structure.

Exemplary Third Stage

In some embodiments, at an exemplary third data extraction stage, the exemplary inventive longitudinal data engine is configured to distribute the extracted XML/JSON files of the relevant subject(s)/object(s) into a cluster of XML/JSON files (303) (searching cluster nodes), as illustrated in FIG. 3. For example, a cluster node that has received the current lowest load would be designated to perform the processing job.

Exemplary Fourth Stage

In some embodiments, at an exemplary fourth data extraction stage, the exemplary inventive longitudinal data engine is configured to scan the cluster nodes of the extracted XML/JSON files of the relevant subject(s)/object(s) to identify the desired longitudinal data by using methods such as, without limitation, XPath over XML or any other similarly suitable techniques. Then, the exemplary inventive longitudinal data engine is configured to extract the identified longitudinal data. For example, the exemplary inventive longitudinal data engine is configured to pass every cluster node once on every subject (e.g., patient) file in the defined cohort in order to identify potential answer to any question.

In some embodiments, the exemplary inventive longitudinal data engine is configured to determine the continuity or the absence of any event relay based on an accumulation of, for example, without limitation, the distinct “HourToNext” data elements.

FIG. 5 illustrates a snapshot of an exemplary control interface that can allow the user to control how the exemplary inventive longitudinal data engine would scan the cluster nodes. For example, via FIG. 5, the user can set parameters that the exemplary inventive longitudinal data engine would move a particular cluster node 5 days before and after the first PTCA and look for ontology(ies) of ST elevation (STEMI) and non-ST elevation (NSTEMI) myocardial infarction.

Exemplary Fifth Stage

In some embodiments, at an exemplary fifth data extraction stage, the exemplary inventive longitudinal data engine is configured to consolidate the extracted longitudinal data for the cohort (population) to produce a respective output that may be used to generate interactive chronological timeline(s) for each subject or object.

As detailed herein, typically, electronic data records on a population of real individuals may have one or personal identifying attributes (identification identifiers), such as, but not limited to, names, birthdays, ages, addresses, zip codes, social security numbers; phones, etc. For example, a cable company may track records of personal viewing preferences together personal identifying information of its subscribers (identification identifiers). In another example, an internet company may track internet activity of its users together with personal identifying information. For example, a typical source electronic medical record (EMR) data object is a collection of electronic health information about an individual or a population of individuals.
